Muller, 23, is the organization’s best pitching prospect yet to debut in the majors. It’s possible, if not likely, he works his way into the bigs next season. Muller’s place on the 40-man roster only helps those odds.
Before spending the shortened season at the alternate training site in Gwinnett, Muller appeared in only two spring training games with the big-league team. He was erratic: Muller walked three, struck out three, hit two batters and threw a wild pitch while recording three outs. Still, it was easy to see Muller’s immense potential.
